TX wait skbs need to be completed when they are done. PCIe part does this inside rtw89_pci_tx_status() during RPP processing. Other HCIs use a mechanism based on C2H firmware messages. Store TX wait skbs inside TX report queue so that it'll be possible to identify completed items inside the C2H handler. Try to do this as similar to PCIe path as possible. When the corresponding TX wait skb is found inside TX report queue, unlink it from there and call rtw89_core_tx_wait_complete() to mark the completion. If the callee waiting for the completion has already timed out, the TX wait skb is placed into TX wait list (like PCIe part does). It's important that during HCI reset all pending TX wait frames should be completed inside hci.ops->reset method before calling rtw89_tx_wait_list_clear().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
